Application filed-July 31, 1319. Eerial No. 314,521.

To all whom it may concern:

Be it known that we, ALeEnrJUELrs and Arman A. Jonnrs, citizens of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Dumping-Trucks, of which the following is a specification.

a This invention relates to dumping trucks, particularly to motor dumping trucks and the body construction thereof, and has for its object the provision of a motor truck body which is so constructed and mounted that it may be readily tilted rearwardly into dumping position or to facilitate loading.

An important object is the provision of a truck body of this character provided with gear actuated means for raising and loweriug the body or rather tilting it upon its axis.

Another object is the provision of novel means for holding the body in tilted position.

Still another object is the provision of a novel catch mechanism for locking the body against tilting movement.

An additional object is the provision of a truck body of this character which will be simple and inexpensive. 1n manufacture,-

highly eflicient in use, durable in service, and a general improvement in the art.

With the above and other objects and ad vantages in view the invention consists in the detai s of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which-- 7 i Figure 1 is a side elevation of a motor truck showing the body thereon in normal position,

Fig. 2 is a horizontal sectional view with parts removed, and

Fig. 3 is a longitudinal sectional view taken from the side opposite to that shown in Fig. 1 and showing the body in tilted position. 7

Referring more particularly to the drawings, the letter A designates the frame of an automobile chassis of any make or type, this detail being immaterial.

In carrying out the invention, use is made of a sub-frame including heavy beams 10 disposed upon the bars of the frame A. and secured. thereto by any suitable means such as U bolts 1 which pass through the beams 10 and embrace the frame bars A. The

beams 10 project beyond the rear ends of the bars A and carry on the undersides of such projecting ends brackets 12 through which extends a shaft 13 which may be conveniently a length of pipe.

The truck body is designated broadly by the numeral 14; and comprises a box like open topped structure 15 supported upon transverse bars 16 carried by longitudinal bars 17 which are disposed against the outer sides of the beams 10 and which extend appreciably beyond the rear ends thereof. Secured upon the under sides of the bars 17 are brackets 18 revolubly engaged upon the ends of the shaft 13. By this construction it will be seen that the truck body is pivotally mounted so that it maybe swung in a vertical plane.

' In order to hold the body down upon the automobile chassis and prevent tilting, there are provided catches 19 which are secured upon the tops of the beams 10 and which project laterally partly over the bars 17. The bars 17 are of course provided with cutout portions 1'? which allow the passage of the catches 1.9 when the body is swung to normal position. Codperating with these keepers or catches are latch bars '20 and 21, the former being pivoted intermediate its ends upon one bar 17, as shown at 22, and the other being pivoted at one end upon the other bar 17 as shown at 23. These latch bars are disposed within shallow recesses 24- and when 1n normal posit on engage beneath the catches or keepers 1 9,: this normal pos1- tion being maintained by means of suitably arranged springs 25. V

In order to effect release of the latch bars from engagement with the'keepers, there is provided a lever 26 suitablypivoted at one side of the body and connected by a link 27 with the forward end of the latch bar 21. This latch bar 21 is, in turn, connected by a link 28 with the rear end of the latch bar 20. When. the lever 26 is properly moved, the forward ends of the latch bars 20 and 21 will swing outwardly and out of engagement with the keepers 1.9 and thus permit the body to be tilted or swung. a

In order that the body 14: may be tilted upon the pivot shaft 13, there is provided shaft 29 journaled transversely of the bars 10 and having one end journaled through a bracket 30 secured upon the frame bars A. This shaft 29 carries at its central portion a pinion 31 which meshes with a gear 32
